This module provides a built-in web interface to view chatroom logs stored by mod_mam_muc.


Same as any other module, be sure to include the HTML template http_muc_log.html alongside mod_http_muc_log.lua.


For example:

Component "" "muc"
modules_enabled = {
storage = {
    muc_log = "sql"; -- for example

The web interface would then be reachable at the address:

See the page about Prosodys HTTP server for info about the address.


The default HTML template lives in http_muc_log.html in the same directory as the module, but can be changed by setting http_muc_log_template to point to a different file. The same template, with different input is used for every view.

The module uses util.interpolation for rendering templates, with the pattern "%b{}" and HTML / XML escaping enabled.

Default view

To link to the latest day instead of calendar from the room listing page:

http_muc_log_default_view = "latest"

Inline images

Inline images can optionally be shown. This is disabled by default for privacy reasons.

http_muc_log_show_images = true

Calendar optimization

The calendar view relies on an optional part of the Prosody archive storage API that provides a list of every valid date. If this is unavailable then the module queries for the first and the last messages and assumes that every date between those is valid. This may lead to many empty pages in case the logs are sparse.

This optimization can be turned off, to get a more accurate calendar view, but it will likely be very slow.

http_muc_log_lazy_calendar = false

Pinned chatrooms

The room list page is normally sorted by address, rooms having a description before those that don’t. To override this, or pin certain rooms to the top:

http_muc_log_list_order = {


Requires Prosody 0.11 or later and a storage backend with support for stanza archives. See mod_storage_muc_log for using legacy data from mod_muc_log.


With the plugin installer in Prosody 0.12 you can use:

sudo prosodyctl install --server= mod_http_muc_log
